Genes affected

SLC37A4 (HGNC:4061): (solute carrier family 37 member 4) This gene regulates glucose-6-phosphate transport from the cytoplasm to the lumen of the endoplasmic reticulum, in order to maintain glucose homeostasis. It also plays a role in ATP-mediated calcium sequestration in the lumen of the endoplasmic reticulum. Mutations in this gene have been associated with various forms of glycogen storage disease. Alternative splicing in this gene results in multiple transcript variants.[provided by RefSeq, Aug 2009]

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Variant summary: SLC37A4 c.492C>T alters a conserved nucleotide resulting in a synonymous change. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 6.9e-05 in 246696 control chromosomes, predominantly at a frequency of 0.00013 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than expected for a pathogenic variant in SLC37A4 causing Glycogen Storage Disease Type Ib (6.9e-05 vs 0.0012), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.492C>T in individuals affected with Glycogen Storage Disease Type Ib and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as likely benign, and one laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest reported MAF 0.01% (9/68046) (https://gnomad.broadinstitute.org/variant/11-119027762-G-A?dataset=gnomad_r3). This variant is present in ClinVar, with multiple labs classifying this variant as Likely benign (Variation ID:302706). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant suggests that this variant does not cause disease but requires further evidence. Therefore, this variant is classified as likely benign. -
